Review: Terrific challenging builds - My overall rating for this wood "build it up yourself" safe is 5 stars, even though each of the three individual categories listed got a 4. It's not easy to build!, but that's good - it's not supposed to be. I do think the quality of the materials is good, consistent, and there are no booby traps involved with the build up, but it's not easy. It's a good gift, but only for the right person who enjoys some complex model building. It has been a great project for my 11 year old son. We have done 2 of these types of wood model builds. He did much more on his own with the second build and we both enjoyed the process. And... the built model is pretty solid, but I wouldn't give it 5 stars for sturdiness (maybe that is unfair of me, as it's as sturdy as you can expect a complex mechanical model to be). But back to the overall rating: oh, it's definitely a 5. Between the quality of the material, the overall well written instructions, and the enjoyment we've had building these types of models, I think it's a great item and I'd be glad to get another for my son to build.
Review: Additional tool recommended - This is one of the better wooden models I've put together. It's very sturdy and the mechanics involved are really cool. People that are saying the combo doesn't work likely ran into what I did. You have to turn the second number more than you would think you do to engage the second wheel. It ends up being like 3 turns to set the second digit. Once I figured that trick out my kid was able to open it up. I do recommend a pair of needle nose pliers, an exacto knife, and a metal file to sand with. The last thing isn't needed, just makes it easier most of the time. Don't skimp on the wax either. I really enjoy putting this together with my son. Good bonding time and now he has a really cool piggy bank.

### ⭐⭐⭐⭐ Great project! unfortunately not all pieces align when putting partial builds together.
*by M***L on March 23, 2024*

This was a great project to build! I spent an hour here and there to put this together. The manual is pictures only, and pay attention (unlike me, at times), sometimes similar looking parts have a different place/ purpose! I've been able to correct such mistakes fairly easily though. Fortunately there was a board with spare parts, some of which I needed due to original parts breaking. Some parts don't lock together well and needed some 'encouragement'. Ultimately everything fit together nicely. However, the safe door lock never worked correctly after I put it together, even though I spent ample time lubricating every moving part. The door remains unlocked permanently. I will attempt my next 3D project with a different company.
